The Examiner must make sure that the candidate understands what he is required to do.

If the candidate answers the questions put to him by the Examiner with complete or very nearly complete accuracy, he should be treated as having passed. If he does not answer with very nearly complete accuracy, he should be treated as having failed.

(8.) The Examiner must take care, by varying the tests in form-vision, and by every other means, to guard against the possibility of any deception on the part of the candidates. The distance at which the candidate must stand, and the standard of vision required, should, however never be varied.

(9.) Every candidate who fails to pass the form-vision test is to be examined with the pellet test, as follows: The pellets should be placed on a white plate, and the first test-pellet (which is of the same colour as the first wool-test skein) should then be placed a little distance from the box on another white plate. The candidate should be required to pick out and lay by the side of the test-pellet all pellets of the same colour. The same should be done with the second and third test-pellets, and the examination should proceed in the same way as the wool test.

(10.) Should the candidate pass the pellet-test, the Form Exn. 17b, together with the remarks of the Examiner, is to be forwarded to the Marine Department for instructions as to whether the candidate is or is not to be regarded as having failed in form-vision.

(11.) Should, however, the candidate fail in the pellet test, thus indicating that the defective form-sense is due to disease, &c., it will not be necessary to submit the case to Wellington, but the Examiner should report the candidate as having failed in form-vision, and in forwarding the usual papers a description of the colours of the pellets incorrectly selected as matches in the respective tests, with any remarks, should be given on the Form Exn. 17c, in the space allotted for the incorrect wools.

(12.) The result of every test in form-vision is to be reported to the Marine Department on the Form Exn. 2, and on Form Exn. 14 when the candidate is up for examination for a certificate, and on Form Exn. 2b when the candidate is up for examination in colours only.

All cases of failure to pass the test are also to be reported to the Marine Department on Form Exn. 17b.

2. COLOUR-VISION TEST.

(1.) The colour-vision of candidates is to be tested by means of Holmgren’s wools.

The wools are always to be kept in the tins provided for the purpose, except when in use at an examination, in order that they may not become faded or dirty. Each set contains about 135 skeins of wool.

(2.) Before the examination commences the skeins should be separated from one another, but each separate skein should be kept tied up as when first received.

The three test-skeins are labelled respectively I. (light-green), IIa. (pink or light-purple), and IIb. (red), and they are always to be used in the order mentioned.

Care must be taken that the labels do not get detached.

The colour-vision test should be held only by daylight. If a good natural light is not obtainable, and artificial light has to be used, the test must be postponed. When the weather is dark or foggy, and a candidate cannot be examined in colours before his examination in navigation commences, he may be allowed to proceed with the examination in navigation, provided he is examined in colours on the first available opportunity.*

Full instructions as to the conduct of the examination will be found herein.

(3.) The Examiner, as the examination proceeds, should carefully place on one side the skeins the selection of which by the candidate seems to indicate a defect in colour-vision, taking care to discriminate between those selected as matching the first test-skein, those selected as matching the second test-skein, and those selected as matching the third test-skein.

The skeins which have been correctly selected should be returned to the general heap on the completion of each of the three tests.

(4.) In every case in which the Examiner rejects a candidate, or is in doubt as to whether he should reject him or not, he is, when the examination is finished, to cut a small piece (say, an inch) off every one of the actual skeins incorrectly selected by the candidate, and to stitch the pieces cut off on to Form Exn. 17c, keeping the pieces cut off the skeins selected as matches to the first test-skein in one line, the pieces cut off the skeins selected as matches to the second test-skein in another line, and the pieces cut off the skeins selected as matches to the third test-skein in a third line on the form. The form (Form Exn. 17c), with the pieces of wool attached to it, is then to be forwarded to the Marine Department, with the Examiner’s report, on Form Exn. 17b.

The greatest care must be taken that the pieces forwarded are cut off the actual skeins selected by the candidate, in order that there may be a reliable record of the actual selections made by the candidate if any question should subsequently arise.

Pieces need not be cut off the test-skeins, but only off the skeins incorrectly selected by the candidate.

(5.) In cases in which the candidate passes the test, pieces need not be cut off the skeins he has selected.

(6.) When the candidate makes incorrect matches the Examiner should, after each of the three tests, hold up the skeins selected, and ask the candidate if he is satisfied that they all match the test-skein. If he is not satisfied he may be allowed to withdraw any of the skeins he pleases.

(7.) During the test for colour-blindness the Examiner should avoid naming the colours of any of the wools, and should explain to the candidate that he does not require them to be named to him.

In the test for colour-ignorance the candidate has to name three colours. (See under heading “Colour-ignorance Test.”)

(8.) As soon as any skein becomes discoloured, or unduly reduced in size (say, by one third) owing to pieces having been cut off it, the matter should be reported to the Marine Department.

(9.) In the remarks which follow reference is made to different kinds of colour-blindness (red-blindness and green-blindness), but the Examiner is not required to form any conclusion as to the kind of colour-blindness from which the candidate suffers, and should not offer the candidate any opinion on this point.

• When the examination in navigation precedes the colour-tests the candidates should be informed that the examination in navigation will count for nothing if they should fail to pass the colour-tests.
